Daddario PW-CT-15 Micro Soundhole Tuner

I thought this was the coolest option for a clip-on tuner - until I got it. There are obvious flaws like not being able to use a soundhole cover during live performances or for humidifying your guitar. The real flaws are in the button placement like when you turn it off/on and the calibration switch is closer to your thumb than the on/off switch, why? In my case, the tab that holds the tuner in place broke off after 3 months of use - for no apparent reason. One day it worked the next day it was broken. I haven't even been playing my guitar that much lately and no one else goes near it. Oh well, now I get to look for another tuner . . . 8^D
